RUBBER HEEL:

7 Application filed October 13,1926; Serial 110,141,259,

My invention relates to improvements in rubber heels and the method of attaching the same, and has for'its objects the. siinplification of thepres'ent practice inthis art.

Among'the objects of my invention are the production of heels'ofthe' kind described, which shall be speedily and ecconomically attached to the shoe, without danger of,

accident-ally becoming detached therefrom in the course of use, will make a job neat and attractive in appearance, shall be simple, and which shall be efficient and satisfactory for use whereever found vapplicable.

Many other objects and advantages of the construction herein shown and described, -will be obvio'us to those skilled in the art to which this invention appertain's, from the disclosures herein given, and to this end my I invention consists-in the novel arrangement, construction andcombination of parts herein shown'and described, and more particularly pointed out in the claim. I v

In the present practice of shoe-making,

I rubber (heels are attached to shoesby driving tacks upwardly through the series of openings through the heel, these tacks entering the leather top lift, outer sole and inner sole, and then clinched down inside the shoe.

When repairing, or replacing the rubber heels, these tacks must be pulled out, andthe new tacks driven back into the same holes previously formed through the outer and inner soles. Obviously the newltacks will not hold as firmly as the original ones unless of a larger size than the ones first driven in.

My invention has among its objects means whereby all of this tacking is done away with, and no new tacks need be handled.

when replacing the heels.

parts throughout the views,

Figure I is a fragmentary portion of a shoe, showin a rubber heel and leather top lift affixed t ereon;

Figure II is a top plan view of the leather topllift of my improved construction.

,the parts" being shown in theirattached relationship;

Figure V is an elevation of an attaching v Figure VI is an elevational perspective of the modified-form of washer; and

, Figure VII is a sectional detailiof the pin,

and washer shown in Figure IV, after these elements larein final position, i j i In the drawings,,wherein I have illustrated the preferredembodiments of my invention there is shown a shoe having the usual or any preferred shape and-s1ze,-1nd 1 cated at S the outer sole being indicated am, As Is customary, a lift- 2, preferably of 1eather, is aflixedto the rear or heel portion" positioned below the lift 2. j o The lift 2 may be afixed to= the:outer sole of the outer sole, and a-rubb r heel R'is by any desired or suitable means, as by tacks 1 or the like, but prior to theaffixing of the I lift to the outer sole, a seriesiofopenings or apertures 3 are provided therethrough. There may vbe any numberof these aper.- tures, arranged in any suitable spacing,:it being noted that there are less than half as the apertures now. provided in rubber heels.

Fastening means 4 areinserted through the apertures 3 of the lift, beforeattaching many apertures required as-compared' with said lift permanently in place,these fastening means each comprisingv a shank portion having'a head5 Vat-oneend, and an annular '2, as shownin Figure III. Obviously the pins 4 will register with the aperturesof the washers 8 of the heel, so that when the rubber heel and the lift are pressed to? gether, the reduced end "of the pins will snap past the washers and interlock therewith, thewashers remaining in such positionthat they will each encircle the reduced or neck portion of their co-operating pin. If d'esired, the washers 8 may be split or'otherwise formed, so as to render them more resilient.

Thusthe heels will v be retained in their attached position until it is desired to removeor'replace the heel. The replacing of the heel is extremely simple, inasmuch asall th fl' 1 it takes is that the old heel be snapped ofl and the new heel be snapped on. u

In order that the heel may be worn down to the extreme limit it is preferable that the inclusive, a typeof heel R wherein the Washwashers be placed near the top of the heel and in order to provide still further wearing qualities I have shown in Figures IV to .VII

er 8 projects upwardly beyond the top surface of the heel, the pins 4t being shorter than that previously. described, and in the present instance terminating within the plane of the lower surface of the lift 2.

These washers 8 are preferably hollow tubes, reduced at their ends and flared out wardly intermediate the ends as shown at 9, so that these washers may be firmly imbedded within the body of the rubber when forming the heel. These washers are preferably split as shown, so as to be exp'ansible and self-contracting, so that when the pin ends 7, enter the washers, the washers will be temporarily expanded, and then will snap back into shape to encircle the ball end of the pin. On account of the projection of the washers and the recessing of the free ends of the pins, the heels must be tightly pressed into place 'when assembling, and when. released, the washers will be interlocked with the pins, and the heel will be retained tightly against the under surface of the top lift 2, until forcibly released for replacement or a like purpose.

' Thus it is seen that I have provided an article that is easy to make in practice, is economical, speedy, and neat. addition, the wearing qualities of the heels 'are increased, for, in the modified form just described, the washers may be worn down flushwith the top of the heel before itis necessary to replace the heel, the shape of the Washer being such as to interfere but slightly with the cushioning effect of the rubber heel. V V

Having thus described my invention, it is obvious that various immaterial modifications may bermade in, the same without departing from the spirit of my invention;

hence I do not wish to be understood as limiting myself to the exact form, construction arrangement and combination of parts herein shown and described, or uses mentioned, except as limited by the claim.

hat I claim as new and desire to secure by Letters Patent is:

In combination, a leather lift adapted to be a'flixed to a shoe and provided with apertures extending therethrough, pins insertable be received within said apertures of the lift to receive the heads of said pins,'and thereby pull said heel up tightly against said lift, the major portion of the washers forming a part of the tread surface of the heel after a predetermined amount of wear of the latter,

so that the entire heel can be worn down adjacent the washer without exposing the head of the pin to wear.
